I've been bothered for years about the state of the plastic door-lock surround - the cover for where the lock "knob" pops up next to the window. They seem to be made out of the same plastic that chocolates are packed in, and now they're all 50+ years old..
I got a 3D printer for Christmas

and decided to try making some of these. It's now in a state where it fits and looks okay from maybe 60cm away. It's a tricky shape with compound curves everywhere, I could probably go on tweaking it but I'm done with it for now. It's also awkward to print since the mounting-pegs and hollow-shape necessitate the slicer-sw to generate a lot of 'supports' for printing
Pictures below - if anybody wants the .STL file to try print their own, then DM me - i'll try to post it somewhere but I think FDF can only host image files.
